Love Bite Chart

  Everyone can make a love bite at someone's neck - but how about the forehead? That again may be too difficult for most. I guess it's high time that someone assembles a Love Bite Chart, so we all know where on the body it's easiest to make a love bite, and where it's harder. Teenagers could then engage in contests, instead of uncreatively leaving marks on each other's necks.
  This could be subject of a fun website or a highly scientific (medical) project.
